摘 要: 采用热等静压(HIP)法制备芯层为Ni-12%W(Ni12W，摩尔分数)合金、外层为Ni-5%W(Ni5W，摩尔分数)合金的Ni5W/Ni12W/Ni5W 3层复合初始坯锭；采用压延辅助双轴织构技术(RABiTSTM)通过直接冷轧及再结晶退火获得Ni5W/Ni12W/Ni5W复合基带；采用X射线四环衍射技术(XRD)及背散射电子衍射技术(EBSD)对复合基带表面冷轧及再结晶织构进行分析。结果表明：冷轧复合基带表面形成较强的铜型形变织构，再结晶退火后复合基带表面形成锐利的立方织构，其立方织构含量达到99.1%(≤10°)，与商业用Ni5W合金基带水平相当。

Abstract:A tri-layer composite alloy ingot was fabricated by hot isostatic presses (HIP) method, in which the outer layer is Ni-5%W(Ni5W, mole fraction) alloy and the inner layer is Ni-12%W(Ni12W, mole fraction) alloy. The composite ingot was cold-rolled using the process of rolling assisted biaxially textured substrate (RABiTSTM) technology and annealed to obtain the Ni5W/Ni12W/Ni5W composite substrate with high cube texture. The cold rolling and the recrystallization textures on the surface of the as-obtained composite substrate were studied systematically by X-ray and EBSD measurements. The results show that a strong deformation copper-type texture is obtained in the cold rolled composite substrate, and a sharp cube texture is formed on the surface of Ni5W/Ni12W/Ni5W composite substrate after a recrystallization annealing process. The percentage of the cube orientated grain within a misorientation angle of 10° is as high as 99.1%, which is in the same level as that of the commercial Ni5W tape.
Key words: Ni-based composite substrate; hot isostatic press; copper-type texture; cube texture
